Theobjeets of thisiinventionare to secure an improved "cup in which plates that -normally 'lie flat-Wise -'together can be bowed *apartlwith their-side'and bottom edges in engagementto 't'orm an interior space or chamber, as tor drinkingpurposes, the cup :normally being "fiat for convenience in packin'g'or carryingin ones pocket; to provide meansfor operatingsaidplates to expand or 'open the cup and :to return it to closed or flattened "form; to secure such operating means as can be permanently connected to the plates to avoid separation and loss; to "provide means for preventing I escape of the plates from each other when the cup is ;closed;'to providean operating lever which is out of the'way when the cup is openedand when it'is closed extends overthe mouth of the cup to protect it, and to obtain other advantages and results asmay be brought out by the following description.

Referring to the acccompanying drawings, in which like numerals of reference indicatethe same parts throughout the several views, V p

Figure 6 is a perspective view of said operating lever. p

In the specific embodiment of the invention shown in said drawings, 1 and 2 indicatesheet metal plates forming the oppo-' site sides of a cup, said plates normally lying-flatwise together. The plate 1 has its 'ma-rginsturned-over as at 3 'to receivethe corresponding margin of the plate 2 and form a closure therewith, especially when the cup is distended or opened as by prescing inward upon the opposite edges of the top of the cup. This causes the plates 1 and 2 to bulge outwardly apart at the top of the cup, as shown in Figure 5, and in decreasing proportion all the way down to the bottom of the cup.

It will be noted that the plates 1 and 2 are of separate pieces, the plate 2 having an edge adapted to fit in thegroove at the edge of the plate 1 when the plates are bulged outwardly apart as describedgandby myinvention I provide means for bulging said plates which will forcesaidedges into gageinent to i'orm a oint. Indeed,-*the said edges can be readily made-softhat a 'jo'int impervious to water orthe lilte is formed when they are forced together by such means as hereinafter described.

The means which I have shown for 0perating said plates to open and close 'thecup consist of a rod or wire l extending across the top otthe cup between thelplates 1 and and projecting through suitable holes in themarginalbend of the plate l'toiform th e flange 8. At one end-said rod e' has a head 5 outside the cup and-at its otherendlit has an eye 6 also outside the cup upon #whichis pivoted an operating lever 7 'by mean's of which the cup is opened and=c losed This operating leverhasa'head 8'with aca'm-surface 9 adapted to ride upon th'e 'edge of *the cup and a handle portion 10 with an end clasp 11. of sheet metal doubled along the'outer edge ofthe handle portion 10, so that itS h'ea'd S is composed of two opposite thicknesses of metal spacedby the wire or rod e bet-ween them, see Figurefi, andthe end clasp is "tormed'by two divergingl'ugs whichstr'ad- 'dle the top of thecup inclosed position'of the sameand hold it closed.

The operatinglever? lies along the topof "the'cup, when the latter is closed, as shown in Figurel, the innerendoft'he cam s'u'r- 'face9 permitting thetop of thecup to expand edgewise and the handle 10 ot -'the 1ever overlying the top of the cuptolfprotect "the same. I hZLVB'SliOXVIlfhB end clasp 1 1 at the middle of 'thetop 'of the cup, but obv'iously it might be otherwise positioned, "or

the handle'portion 10 of thelever might be extended beyond the end claspto-cover more of thetop ot the cup than shown.

To open the cup for use the lever is thro'wn Preferably this lever 7 is made outw-ardl 7 into the position shown in 'Fi' be made in manufacturing my invention, without departing from the spirit and scope oi the invention, and therefore I do not wish to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.

Having thus described the invention, what I claim is:

1. The combination with a cup having a portion providing a groove extending between separated points of the top of the cup downwardly toward the bottom of the cup, and a separate plate with an edge adapted to fit said groove, of means for springing said grooved portion into engagement with said edge of the plate.

2. The combination with a cup having a portion providing a groove extending between separated points of the top of the cup downwardly toward the bottom of the cup, and a separate plate with an edge adapted to fit said groove, oi means for springing said grooved portion into engagement with said edge of the plate and looking it there.

3. The combination with a cup having a side plate providing a marginal groove, and a separate side plate with an edge adapted to fit said groove, of means for bowing said grooved side plate into engagement with said edge of the other plate.

4. The combination with a cup having a side plate providing a marginal groove, and a separate side plate with an edge adapted to fit said groove, of means for exerting pressure upon opposite edges of said grooved side plate to force it into engagement with said edge of the other plate.

5. The combination in a cup having a portion providing a groove extending between separated points o1 the top of the cup downwardly toward the bottom of the cup, and a separate plate with an edge adapter to fit said groove, of means attached to said grooved portion for forcing it into engagement with said edge of the plate and for preventing escape of said plate when it is not so engaged.

6. The combination in a cup having a portion providing a groove extending between separated points of the top of the cup downwardly toward the bottom of the cup, and a separate plate with an edge adapted to fit said groove, of means attached to said grooved portion for forcing it into engagement with said edge of the plate and for overlying the mouth of the cup when collapsed.

7. A. cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, a rod extending between said plates and outward at one edge thereof, and means on said rod for exerting pressure upon the edge of the cup.

8. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, a rod extending between said plates and outward at one edge thereof, and means mounted on said rod for bowing said plates apart.

9. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, a rod extending between said plates and outward at one edge thereof, and a cam on said rod for engaging the edge of the cup.

10. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, a rod extending between said plates and outward at one edge thereof, and an operating lever on said rod having a rest to engage the edge of the cup and hold it open.

11. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, and a bowing lever having a handle which when the cup is closed extends over the mouth thereof to protect it.

12. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, and a bowing lever having a handle with means thereon for holding the said plates in closed position.

13. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, and a bowing lever having a handle with an end clasp to straddle the said plates in closed position.

14. A cup comprising p ates adapted to be bowed apart with their side and bottom edges in closed relation, and bowing means having a portion extending over the mouth of the closed cup to protect it.

15. A cup comprising plates adapted to be bowed apart with their side and bottom edges in closed relation, and a bowing lever 0t doubled sheet metal having a portion straddling the said plates in closed position.
